Application med anuary end of the ap indicia for enabling the user toV alter it to all smaller sizes; to provide a tire flap already apertured :for the largest size and having indicia for the user to properly aperture it for smaller sizes; to 4enable an`y surplus end portion of the tire flap to bev cut oli' YatLthe right point after the flap has been apertured; to thus avoid undue overlappinvf of the ends of the tire flap; to thus provide a tire flap which can be quickly'and 'accurately 'altered for any given size of tireuand yet shall at all times provide a complete closure'without overlapping portions, yand to obtain other advantages and so results as may be brought out by the follow.-

ing description. Referring/'to the 'accoin'mnyino` drawing, iuwhieh thesame numerals of reference designate corresponding and like partsathroughout the several views,

4Figure l is a view of the outer side or' a flap ogmy improved construction extended `and with a portion intermediate its ends broken away.

Figure 2 is an edge View of the same;

Figure 3 is an edge view of the adjustable end et the improved tire flap pinched or folded along a longitudinal median line for :iper-turing, and

Fi ure 4 is an outer side View of said adjusta le end after ithas been apertured for use as 'a No. 3 flap and its surplus end portion cut oi. i

n'the specifcembodirnent of the invention shown in said drawings, 1 indicates a tire iap of any suitable material or composition such as is commonly Aplaced between lthe inner tube and adjacent edges otrthe v shoe or casing to cover the opening through 45 which the inner tube has been inserted, as

-is common in pneumatic tires. Said tire flap is provided at one end with an aperture 2 to receive the valve stem ofthe inner tube upon startin to insert the tire, and it will be understoo that it is desired to have the op osite end of the tire flapapsrturel Ato simi arly'receive-the valve stern when the tire flap has 'been 'put in place extending clear\a\rou11d the innery circumference of the ample. he knows that 'he shoul tube and\tire.

w ferent sizes of tires, and it is common in 'the art known as No. 'i to No. 5, each being for. certain designated sizes of tires and each. having in its adjustable end three holes any one voi which may receive the valve Stern when the tire flap is in place. further understood that it is not possible to cut the entire series of fifteen holes in the longest or No. 5 tire flap, because for the` larger sizes of tires a portion of the holes would be exposed and the tire flap would not ellect the closure' for which it is intended;

to'sell tire iaps in live diderent lengths It #will -be '1 l also if the opposite end of the liap were exn tended so as to overlie said exposed apertures it would produce a long free end which if it stays in place causes an objectionable overlapping or double thickness of the dupfor a eonslderable distance and ir it slips laterally' out o place causes an unevenness which injures the inner tube. Again it will be understood that the aperturing of a tire flap must be done with considerable-exact.- ness and accuracy or otherwise a fullness or a tightnesswill be produced which is not apparent when. the flap is being inserted but which will Acause serious damage after thc tire is inflated. n v

In order to avoid all these dillioulties and, yet secure a tire flap which yshall be alter-- able for all sizes of tires, Iniakemy improved tire lap of the maximum, length of tire tia s of a length equal to that of a No. o tire. ap ind aperture its extreme end portion as attrl 1,52, 53 asA would be donein a No. 5 flap which is the flap used for 35M, 36x41/2 an 372:5 tires. ln series-with said apertures 1, 52, 531 stamp, print or otherwise mark upon the tire as at di, 4t2, 43 the proper location for apertures for a No. 4 lap, as at 8l, 32, 33. the proper location for apertures for' a No. 3 flap as at 2l, 22, 23 the proper location for apertures for a No.2 flap, and as at 11, 12, 13 the proper 'location for apertures lfor a No. 1 lla Adjacent each group of holes for a di erent length Hap is referably .printed or otherwise l displayed the tire sizes for which that group of holes is to be used and also the number of. tire tlap heretofore in use to `which saidgroup 'o holes corresponds. Elius a purchesenknowsthat `heretofore `lie has .used a No'.A 3 p, `tor ex rture this fapfat 31,32 and (1r-soin' oneof there,- l

,and if" he did not know the number of flap whichhe had been usingl but knew that his tire'slwere 33X4,'or example, he would see i I flapnee'dsa No. 5 flap or a Hap for a 35x4,

36x41@ or 37x5 tire he will use the tire Hap justas he purchases it. But if as already supposed he Wants a No. 3 tire flap or one for a 33x4 tire, he will aperture my improved tire flap at 3l, 32 and 33, which is readily done by pinching or folding that .portion of the iiap upon a longitudinal median line, as shown in Figure 3, and cutting;` out with a pocket knife or the like the portion or portions of it necessary to form the aperture or apertures, as shown in Figure 3,

a cut-out portion being there designated by reference numeral 4 and the' aperture by reference numeral 5. Figure 4 shows the tire flap flattened out again with all the "aperl tures 5, 6 and 7 for a No. 3 flap formed and also with the surplus endl portion 8 of the tire flap cut oil' as at 9. 'This surplus end portion 8 is discarded and the user has left a No. 3 flap which can be used the-same way as'No. 3 iiaps which have been sold heretofore. The purchaser-has had to do nothing tothe flap which he bought except make the four cuts described, and at the same time it is' as accurate and sure to fit properly as the No. 3 flap whiehhas been heretofore sold one of the series of ve distinct liaps. Anyr' one of my improved flaps is thus adapted to be used 4for any size tire', and in carrying; stock it is unnecessary to carry the needed number 'of five different lengths of iiaps and the stock needed to be carried is only onefifth of what it .has been with the series of flaps of diii'erent lengths.

Son'ie'variations of details may be -made in l-lavirrsr thus described the invention, whatl Y I claim is: l I

l. A tire flap havingat an imperforate portion oi' itself near one end indicia for aq'ierturin;l said imperforate portion to make the flap any one of a plurality of sizes.

2. A tire flap apertured at one end portion of itself for a certain size and having upon its imperforate portion adjacent said apertured end portion indiciafor aperturing said impert'orate portion to make the flap a smaller size.

3. A tire Hap aperturcd at one end portion of itself for a. certain size and having upon its imperiorate portion adjacent said apertured end portion indicia for aperturing said imperforate portion to make the flap any one ot' a plurality of smaller sizes.

4. A. tire flap having at an imperforate portion of itself near one end indicia for' apex-turing said imperiforate portion to make the" Hap any one ot' a plurality of sizes and for transversely cutting oil' so muclrof the end portion of the lal'ias will be superfluous lupon such aperturing;

5. A tire Hap apertured at one end portion ol itself for a certain size and having upon its imperforate portion adjacent said apertnred end portion indicia for aperturing said impertorate portion to make the flap a smaller size and Jfor transversely removing so muchoi' the end portion ofthe original flap as will be superfiuous for said smaller size.
